Doctor M'Benga was played by Booker Bradshaw. He appeared in "A Private Little War" and "That Which Survives".

This character was actually created by Darlene Hartman, in her purchased (but never produced) TOS script entitled "Shol". The notes for that script give Dr. M'Benga's first name as "Joseph", and note that he was originally a native of Uganda. His brother, Commander Simon M'Benga, was the first officer of USS Hope, a Federation hospital ship, in the planned-but-never-developed Star Trek spinoff Hopeship. [1]

An early draft of the script for "Obsession" (dated 6 September1967) included a character by the name of "Nurse M'Benga". However, in research notes submitted for that episode (on 29 September 1966), de Forest Research noted, "M'Benga is the name of a doctor in 'A Private Little War'."

In a later inter-department communication between Gene Roddenberry and John Meredyth Lucas (dated 2 October1967), Roddenberry noted that regarding "Nurse M'Benga. There is no such Nurse existing on our spaceship. If we need a Nurse, we use our semi-regular Nurse Chapel."

The first draft script for "That Which Survives" misspelled this character's name "Mboya".
